Answer 2

Answer:

6 metre

Step-by-step explanation:

Length= 15m

Bredth= 10m

Height= ?

Area of floor and ceiling = area of 4 walls

Area of floor and ceiling = 2(15*10)

=300m2

Area of 4 walls = 2(15*h) + 2(10*h)

=2(15h)+2(10h)

= 30h+20h

= 50h

Area of floor and ceiling = area of 4 walls

300m2= 50h

300/50 = h

6 = h

6m = h
